　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, stacking product quality instructions inspection rules, and transportation of autoclaved aerated concrete blocks.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Xiajin, Texas,　　The new building material produced by the aerated block equipment is characterized by light bulk density, high insulation efficiency, good sound absorption, and the ability to　　Control standard for radioactive substances in building materials mixed with industrial waste - Determination of steady-state thermal resistance and related characteristics of insulation materials - Protective hot plate method for testing the performance of aerated concrete - General rules - Test methods for volumetric density, moisture content, and water absorption of aerated concrete - Mechanical properties of aerated concrete - Test methods for drying shrinkage of aerated concrete - Test methods for frost resistance of aerated concrete ( - Terminology of bricks and blocks Product classification Specifications: The specifications and dimensions of the blocks are shown in Table Temirlanovka,　　There are six levels of volumetric density: B, B, B, B, and B　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　 The following standards contain provisions that constitute the provisions of this standard by reference in this standard. At the time of publication of this standard, all versions shown are valid. All standards will be revised, and all parties using this standard should explore the possibility of using the latest versions of the following standards.

　　There are seven strength levels: A, A, A, A, A, and A　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　 Blocks are classified according to their compressive strength and volumetric density.Pursuit of excellence,　　 Blocks are classified according to their compressive strength and volumetric density.　　Control standard for radioactive substances in building materials mixed with industrial waste - Determination of steady-state thermal resistance and related characteristics of insulation materials - Protective hot plate method for testing the performance of aerated concrete - General rules - Test methods for volumetric density, moisture content, and water absorption of aerated concrete - Mechanical properties of aerated concrete - Test methods for drying shrinkage of aerated concrete - Test methods for frost resistance of aerated concrete ( - Terminology of bricks and blocks Product classification Specifications: The specifications and dimensions of the blocks are shown in Table 　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size product grade, and standard number.

　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Quality Assurance,　　 Blocks are classified according to their compressive strength and volumetric density.　　Due to its high water absorption rate and drying shrinkage rate, concrete blocks are prone to wall problems after use in construction projects　　 The following standards contain provisions that constitute the provisions of this standard by reference in this standard. At the time of publication of this standard, all versions shown are valid. All standards will be revised and all parties using this standard should explore the possibility of using the latest versions of the following standards.Xiajin, Texas,　　 Block product marking: Mark in the order of product name (code ACB), bulk density level, specification size, product grade, and standard number.　　There are seven strength levels: A, A,Xiajin, Texas block, A, A, A, A, and A　　 Blocks are divided into three levels based on dimensional deviation,Xiajin, Texasaerated block brick, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).
